BALLBEARING.

Specification of Letters Patent.

Application filed. May 6, 1907. Serial No. 371,950.

To all whom it may concern:

Be it known that I, ROBERT G.- CORN- FORTH a citizen of the United States, residing at eymour, county of New Haven, State of Connecticut, have invented a new and useful Ball-Bearing, (Case 13,) of which the following is a specification.

it This invention has for its object to provide a4ball bearing adapted for general use, in which the numberof parts shall be reduced to he minimum and all of which may be easily and inex ensively formed from sheet metal and may e assembled and secured together in the quickest and least expensive manner possible.

a With these ends in view I have devised the simple 11d novel three-part ball bearing of which t 1e following description in connec-- tion with the accompanying drawing is a specification, reference characters being used to indicate the several parts.

igure 1 is an elevation of my novel bearing; and Figs. 2, 3, 4,; 5, and 6 are sections on the line zx in Fig.1, illustrating slightly variant forms in which I have carried the in vention into effect.

. My novel bearin comprises three parts only and a set of bal s.

The essential feature of the invention is that the balls lie between two members which are secured together by. a ring lying wholly within and engaging the outer member and acting to retain the parts in the assembled position.

10 and 11 denote the members, 12 the ring and 13 the balls. Member 10 comprises a ring-she ed portion indicated by 14 which is rovid'e with an inwardly-turned flange inicated by 15, at the edge of which on the innerside is ali 16 which forms a cup to retain the b'alls be ore the parts are assembled. Member 11 consists of a ring-shaped portion indicated by 17 which is provided with an outwardlyturned flange 18 which lies loosely within ring-shaped portion 14 of member 10, thus 'formmg between said members a ball race indicated by 19,, The ring-shaped por-- tion 14 of m'ember 10 extends horizontally be yond the outwardly-turned flange 18 of member 11,formin a circular space or chamber 20 outside said ange which receives ring 12. This ring lies wholly within the said space, covers the joint between the members and re-' tains the parts in the assembled osition. The ring may engage the wall of the space with a drive fit, as iii-Figs. 2 and 5, or may be a spring ring and engage the wall of the space by its outward expansion, as at 120 in Figs. 3, 121 in Fig. 4, and 122 in Fig. 6. In the last mentioned forms a socketfll may be formed in the wall of space 20 to receive the ring. In all of theforms members 10 is left free to rotate independently of member 11.

Having thus described my invention, 1

claim:

A ball bearing comprising an-ou'terfringshaped sheet metal member having an inwardly-turned flange with a lip on its inner edge, for the purpose set forth, an inner ringshaped sheet metal member lying Within said an outflange, said inner member havin wardly-turned flange lying within t e edge of the outer member whereby, a ball race is formed between said members and a circular space or chamber is formed outside the flange of the inner member, a set of balls in said race and. a ring inclosed in said space and engaging tn'outer member closely, leaving the inner member free to rotate independently thereof.

In testimony whereof I afilx my signature, in presence of two witnesses.
